Very cool system designed to fit onto an existing carbed motor. No fuel return line needed! Special fuel pump only pumps fuel when ECU tells it to. Checkout the install vid.

This was in last months Hot Rod if i recall. Also, Alex, thats all the power the fuel injectors can handle. If you wanted more power you'd need two systems like the EZefi allows for. Neither "self tuning" systems support power adders. The nice thing about the MSD is the spark control that the EZefi does not support. I would rather see the return line on the fuel line though.

But they claim with the newer computer controlled fuel pump the injectors only get the fuel they need and there's no extra fuel to return. Makes sense.

I didnt realize that the pump was a pwm pump. I would now rather have the pwm than the return style. The price it too high imo at $2300 with pump and line or $2000 base. The only real "better" thing about MSDs system compared to the much less expensive FAST is te spark control and the integration of a MAP sensor which leads me to believe that they are going to try and support boosted applications.
